ServoTek Products Inc. announced the successful application of its TachSyn Series brushless DC tachometer/commutator within industrial motor speed monitoring applications. The high-accuracy TachSyn ...

A minimal observable length is a common feature of theories that aim to merge quantum physics and gravity. Quantum mechanically, this concept is associated with a nonzero minimal uncertainty in ...

Schrödinger operators, typically formulated as −Δ + V where Δ denotes the Laplacian and V a potential function, are central to quantum mechanics and spectral theory. A key focus in recent ...

Abstract: The 80 kV, 250 kA commutator consisting of two series-connected triggered vacuum switches (of type TVS-43) has been manufactured and tested. The measurements have shown that the voltage ...

Abstract: In the use of the synchronous commutator in series connection as a suppressor, serious errors may arise due to relatively small amounts of capacity in the commutator and galvanometer ...

The main result of this paper is a vector valued commutator theorem for operators which includes, as particular cases, the known results on the commutator of the Hilbert transform. Applications to the ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...
